Application filed April 11, 1930. Serial No. 443,403.

The present invention relates generally to 1 ice cream freezers, and more particularly to a construction designed for use in conjunction with a washing machine, so that the freezer can be partly'arranged within the cylinder of the washing machine, and operated by the power shaft of the latter, and thereby obtain desired results in a quick and convenient manner. 7

10 In carrying out my invention I contemplate a novel construction of means for associating the freezer can with the power shaft of the washing machine, which permits of the freezer in its entirety being quickly and'conveniently associated therewith or removed therefrom as desired.

The invention further comprehends the provision of a novel construction of means for adjustably supporting the freezer in its entirety with relation to the cylinder of the washing machine, to facilitate the association or removal of said parts as the occasion may re uire.

i nother object of the invention resides in I the provision of means for holding the dasher or agitator stationary, while ra idly rotating the freezer can about the latter rom the power shaft of'the washing machine.

Other objects and advantages will appear :50 when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement 0.1.. parts hereinafter claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein; I a

of the bottom of the outer casing of the freezer, and its associated parts.

Figure 7 is a bottom plan View of the freezer can. 7 V v Figure 8 is a fragmentary bottom plan view of the freezer, illustrating the coupling between the latter and the power shaft of the washing machine. i

Referring to the drawings in detail, 10 indicates the cylinder of a washing machine of any ordinary or well known construction, which cylinder is supported upon a base 11 provided with legs 12. The motor for the machine is indicated generally at 18, while operating within the cylinder is the power shaft-14 suitably geared with the motor, and ordinarily utilized to support and rotate within the cylinder 10, a clothes receiving receptacle not herein shown. q

As hereinabove pointed out, the invention contemplates the provision of an ice cream freezer constructed to permit of its association with the power shaft 14 of the washing machine, so that the freezing operation can be quickly. and efliciently performed. lVith this object in view, the invention therefore contemplates the novel construction of means for associating the freezer with the power shaft 14, so that the freezer can be quickly and conveniently associated with the power shaft foruse, or removed therefrom when desired. The preferred embodiment of the invention for this purpose is herein illustrated, and will be specifically described here- The ice cream freezer embodies an outer casing 15 which may vary in size and be constructed from any suitable material without departing from the inventive idea, and which outer casing receives the usual freezing agent, while arranged within the outer casing is a freezer can indicated at 16. This can 16 may also vary in size, and is mounted for rotation with relation to boththe outer casing 15 and the dasher or agitator which it receives. The can 16 is provided with a flanged removable cover 17, and risingcentrally from this cover isa hollow boss 18, constituting one of the bearings for the can 16. This hollow boss 18 is received by a suitable opening formed centrally in a substantially flat bar arranged transversely across the top of the outer casing 15, and herein indicated at 19. One end of this bar 19 is slightly reduced to be slipped within a loop 20 supported by and projecting central opening formed therein for a purpose to be presently described. I

The dasher or agitator arranged within the freezer can 16, preferably embodies a shaft 24, the lower end of which is formed with a tit 25 received by a suitable bearing 26 carried by the bottom of the freezer can 16, while the upper end of the shaft 24 passes through the hollow boss 18, and is provided with a squared extremity 27 received by the squared opening in the bracket 23 above referred to. By reason of this construction, it is manifest that the dasher is held fixed with relation to the'outer casing 15, and that the freezer can 16 isrotated about the dasher from the power sha it 14 of the washing machine. Carried by the shaft 24 are'upper and lower transverse arms 28 which terminally support vertically disposed scraper blades 29, while also supported by the arms 28 are spaced parallel inclined blades 30. which by reason of their angular relation with respect to the shaft 24 materially accelerate the freezing operation. It is manifest from the construction thus far described, that the freezer can 16 can beeasily and quickly removed from the outer casing 15 for any purpose whatsoever, as it is only necessaryto remove the flat bar 19 from the top of theouter casing, a ter which the can 16 can be easily lifted from the casing as will be readily appreciatedl For the purpose of partly supporting the ice cream freezer within the cylinder 10 of the washing machine, 1 preferably employ an annular base 31 which reposes upon the bottom of the cylinder and surrounds the power shaft 14. This base is preferably constructed of wood, while arranged upon the base is a metallic ring 32, the latter being preferably secu-red'tothe base by suitable fastening elements 33. Rising from this'base, and securedto the metallic ring 32 is a plu rality of rods 34'which may vary in number, and slidably received by suitable bracket lugs 35 carried by the outencasing 15. Each bracket 35 is provided with a thumb screw 36', which when tight against the rods 34, hold the freezer fixed relatively to the rods.

Manifestly the weightof the freezer is supsecured to the bottom of the other casing as clearly illustrated in Figure 3. This tubular member 37 constitutes a bearing for the bushing 40 which itreceives, and this bushing 40 is' formed with an annular'flange 41 which reposes upon the flange'38 of the tubular member 37. It willbe noted upon inspection of Figure 3, that the lower end of the tubular member 37 is slightly spaced from the bushing 40 to receive or accommodate a suitable packing 42 and this packing is held in place by a ring-like member 43 carried by the flanged nut 44 threaded on thelower exlike member 43 which retains the packing in place is preferably secured to the nut 44 by suitable fastening elements or bolts 45. The bushing 40 is formed with a recess in its lower end as clearly illustrated in Figure 3, to accommodate a coupling membe'r46, which is held associated with the bushing 40 by means of a suitable fastening element 47. The coupling element 46 is in the nature of a nut having a bore of such cross sectional contour to accommodate itself to the power shaft 14 of similar contour, and the present invention contemplates the use of a coupling member similar to that indicated at 46, having bores of different cross sectional contours, so that a coupling member of any particular cross sectional contour can be readily inserted within the recess of the bushing 40 to accommodate itself to a power shaft of any particular configuration. In this manner, the invention is susceptible for use in conjunction with the washing machine of any ordinary or well known construction, irrespective of the cross sectional contour of its power shaft 14. Rising from the top of the bushtremity of the tubular member 37. The ringing 40"is a hollow boss 48 which is snugly i received by a ring-like member 49 carried on the under side of the bottom of the freezer can 16 as clearly illustrated in Figure 3, and this ring-like member 49 is provided with a pair of diametrically opposed openings 50 as connection between the bushing 40 and the freezer can 16. p

In practice, when it is desired to make use of the ice cream freezer, it is only necessary screws 36, the freezer to remove from the power shaft 14 the usual well known clothes recelvlng receptacle (not shown) from the cylinder 10 of the machine.

The freezer and its supporting structure here inabove described is then arranged within the cylinder 10, and by loosening the thumb proper can be slightly adjusted upon th rods 34 to facilitate the connection of coupling between the power shaft 14 and the freezer can 16. After these parts have been properly coupled together, the thumb screws 36 are tightened so that the weight of the freezer will be borne by the rods 84, and the motor 13 is then operated to rotate the shaft 14:. As the freezer can 16 is coupled with this shaft 14, it is manifest that the can 16 will be rapidly rotated about the agitator or dasher and by reason' of the construction of the latter, the freezing operation will be accelerated, and the desired result more quickly and eflectively obtained.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood,

I desire to have it known that I do not limit myself to what is herein illustrated and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.
